The control valve was adequately controlling the process, but the actuator required more thrust than typical to move the valve back and forth. The OVD technology detected that hysteresis had quadrupled in one month and found that positioning accuracy was poor.

Although noise problems with steam turbine control valves have existed before, they have become more prominent with nuclear turbines, whose valves range to 20 in. in diameter. Our first

Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as Automatic Control Valves. The hydraulic actuators will respond to changes of pressure or flow and will open/close the valve.

In such industries, control valves are an essential component of the systems used to control important operational parameters like pressure, temperature, liquid levels and flow rates.

The pressure control valve consistently seals the battery system against standard pressure fluctuations of

Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as Automatic Control Valves. The hydraulic actuators will respond to changes of pressure or flow and will open/close the valve.

The key to control valve performance is creating a measurable change in flow through the valve in response to small, input step changes (1% and less). A change in flow indicates that the valve's flow coefficient has actually changed in response to a change in the input signal.

In such industries, control valves are an essential component of the systems used to control important operational parameters like pressure, temperature, liquid levels and flow rates.
